Schedule 18 calls it rural, not urban. A notable difference.

As one example, compare Schedule 18 K values with AT's design guide or TAC and you'll see it's overkill. This is a consistent trend in Schedule 18 to make the road "safer".

I disagree only because the road feels too open. The barrier free requirement and inflated "110" design standards makes everything that would slow a driver down non-existent. The 85th percentile speed on Stoney is probably Coquihalla bad.
